“So how does a vocal harmonizer work?”

To put it plain and simple, a vocal harmonizer takes the vocals you’re singing into the microphone, and raises or lowers the original pitch. While you’re singing, it simultaneously sends the pitch-altered version into the speakers. Essentially, vocal harmonizers provide you with backing vocals.

You can manually adjust the type or the pitch of backing vocals you want the pedal to provide you with. But some devices have a cool feature which allows them to “listen” to what you’re performing on your instrument at the moment and automatically provide you with the type of backing vocals you need at that specific time. This is a very cool feature typically associated with high-end items, so if you’re able to get your hands on one of these models, we say go for it.

“Do I need a vocal harmonizer?”

Much like with every effect pedal, it depends. If you don’t perform live often, the need for having a vocal harmonizer significantly drops, since you can sing a countless number of vocal lines yourself in the studio.

But if you are a live performer, then a different set of question arises. Do you perform on your own or with a band? If you’re on your own, you will definitely need the best vocal harmonizer pedal you can afford. Believe us when we say it, a proper pedal will boost your quality performance through the roof.

If you’re with a band, then it all depends on how well your bandmates can cover backing vocals. If they’re not too good, well, get a vocal harmonizer.

But even with a vocal harmonizer, you need to get your singing chops right, so get to practice!
